// A thread-local data structure that collects all errors emitted by APIs
// into one unified structure. This library has 2 core tenets when handling
// errors
//
// 1. Pipelining of errors
// Errors emitted over the course of several API calls are accumulated
// into a thread-local sink which save the error code and message
// of the first error encountered.
//
// 2. Error proof APIs
// Functions that produce errors must return objects/handles that are
// marked to trigger no-ops used in subsequent functions dependent on it.
//
// Together this allows end-users of APIs to chain calls and defer error
// checking until the end of a sequence of actions. Consider the following
// example demonstrating the 2 approaches.
// (A) Conventional error checking patterns using return/sentinel values
